Abstract

Using GEPD data from Peru, this paper examines the psychometric properties of the ECD assessment module. We produce summary statistics of the fraction correct overall, by subdomain, and at the item level. We examine the test reliability of our domains. We then compare our results to data from a similar assessment used in the MELQO project in Peru.

Takeaways:

Summary Statistics of Data

Before estimating the model, we begin by examining summary statistics and missing values in our item response data. To begin, we will show summary statistics of the fraction correct on the literacy, math, socio-economic, and executive functioning sections of the examination, as well as the fraction correct on broad sub-domains.

The sub-domains for the literacy section are:

The sub-domains for the math section are:

The sub-domains for the socio-emotional section are:

The sub-domains for the executive functioning section are:

Inter-Item Correlations

Next we display inter-item correlations for our 1st grade assessment.

Reliability and Internal Consistency

In Psychometrics, internal consistency is an estimate of test reliability. Cronbach’s Alpha (and other internal consistency coefficients) can take values between 0 and 1, being tests more consistent as the value of this coefficient approaches to 1.

In addition to the internal consistency coefficient for a construct, internal consistency analyses also include item level statistics of internal consistency and item discrimination. You will notice in the output of the alpha() function three additional data frames: Reliability if an item is dropped, Item statistics, and Non missing response frequency for each item. We are interested in the first two data frames.

In the case of the data frame “Reliability if an item is dropped”, we need to check what happens with the overall Cronbach’s alpha reliability when a given item is excluded from the analysis. This analysis allows us to identify inconsistent items when Cronbach’s Alpha increases once a given item is excluded. This information will be shown in the first column of that data frame.

In the case of the data frame “Item Statistics”, we want to identify the item correlation with the construct observed total score when the item is excluded from that total score. Ideally, we want items with a positive correlation between each item and the total score, otherwise that item is probably not measuring the same construct as the others, does not correctly discriminate among examinees, or has a problem in either its content or scoring procedure. From this data frame, we are interested in the fifth column titled “r.drop”.

Internal consistency for literacy items. Cronbach’s alpha = 0.80. Good reliability

For each of our constructs, we report: Cronbach’s alpha for the whole test, Cronbach’s alpha increase or decrease when a given item is removed, and item-total construct score correlation (which is a CTT estimate of item discrimination).

MELQO Peru 2017 Comparison

Next, we examine how students in Peru compare to students in a previous round of the MELQO survey. A MELQO survey was given to students in Peru in 2017. The children in the MELQO survey were in pre-school (Kindergarten), and are roughly one year younger on average than our 1st grade sample for the Dashboard. This complicates the comparison, as we would expect the younger children in the MELQO - 2017 assessment to perform worse than our Dashboard children. The assessment used the is very similar to the one used in the Peru Dashboard survey. In fact, the Peru test instrument was taken directly from the MELQO instrument, with a few modifications.

The list of overlapping items is below.

In the table below, we show summary statistics for the 1st graders in the Dashboard survey and the Pre-schoolers in the 2017 MELQO survey. Overall, as expected, the 1st grade students perform much better on the assessment compared to the Pre-schoolers.
